To all whom, it 771/04 oncern:

Be it known that I, FRANZ Josnr HUGO I MAXIMILIAN BERBERICH, a citizenof Geri many, residing at Kiel, Germany, have inparatus for MechanicallyMixing or Combining Liquids and other Fluid Substances, of which thefollowing is a specification.

This invention relates to an apparatus for mechanically mixing orcombining liquids and other fluid substances. The apparatus may be usedfor combining skim milk with oils and fats to form fodder, for mixingsalves, for mixing fats and milk to form margarin, for combining watery,oily, fatty In the accompanying drawing: Figure 1 is a side elevation ofmy improved mixing apparatus; Fig. 2 a longitudinal section t ereof online 22, Fig. 1; Fig. 3 a detail side view of the grooved plug, and Fig.4 a longitudinal sectionthrough the preliminary mixing body.

To a pipe 14 is connected a socket 15 pro vided. with a lateral branch16 through which are discharged the liquids, after they have beenthoroughly 'mixed. A spindle v17. passes through the end of socket i5and is tightened by means of a stuffing box 18. A plate-2O secured tosocket 15 by bolts 19, is providedwith an inner screw thread forreceiving the screw-threaded portion of spindle 17, on the rear end ofwhich is mounted a hand wheel 21. In front of spindle 17 there ismounted in pipe 14, a cylindrical plug 22 having a coned front end 22*,such end being ground against a conical seat 14 of pipe 14. Thecylindrical body of the plug is provided with one or more screw threadsorspiral grooves 22 The plug is. adjustably held The screw thread orthreads 22 form in pipe 14, one or more passages through which theliquids are made to pass. These liquids cause the plug 22 .to rotate, sothat the liquids passing as narrow as possible, are triturated betweenthe inner wall 14 of pipe 14, and plug 22, this trituration naturallyeffecting a thorough mixing of the liquids, so .that separation of themixture into its constituent parts is prevented.

With fats, or fatty or thick substances, the operation must be carriedon at a temperature at which the fats or other substances are veryfluid. With milk this temperature should be at least 50. C., but mustnot exceed to (1., as otherwise the albumen would coagulate, which wouldrender the mechanical mixing difficult.

In' order to effect a still more perfect and intimate mixture orcombination of the liquids, they may bepassed over the surface of a body41 arranged in pipe 14 in front of plu 22. This body is provided withany desire number of projections 42, preferably formed by one or moreintersecting right and left screw threads. After passing this body, theliquid is split up and finally mixed and combined by plug 22.

What I claim is:

- 1. In an apparatus for mixing liquids, the combination of a pipehaving a coniform seat, with an enclosed rotatable plug having acylindrical threaded section engaging the pipe, and a coniform sectionengaging the seat, substantially as specified.

I 2.; In an apparatus for mixing liquids, a pipe and means for forcing aliquid through said pipe combined with an enclosed body 'rovided withintersecting right and lef iiand threads, substantially as specified.

3. In a machine for mixingliquids, the combination of a pipe withanenclosed rotatable grooved plug having a coned end, an independent bodyhaving projections and arranged in front of the plug, and means forconveying liquids under pressure to the pipe,

substantially as specified.
